"Oh, I am!" returned the captain, laughing. "I'm one of Uncle Sam's noblest heroes! He hasn't realised it yet, because I've not had a real good chance to prove it, but I shall, some day."

"Perhaps you could show other people, without waiting for Uncle Sam's turn."

A slight earnestness in Patty's tone made Captain Sayre look at her quickly.

"I'll show you now," he said. "Give me chance for a brave, heroic deed, and watch me hit it off!"

"I will!" said Patty, with twinkling eyes. "But it's Secret Service. I mean Sealed Orders. I'll lead you to it, but you may 'hit it off' without realising it."

"Lead on, fair lady! From now, you are my superior officer."

But Patty turned the subject then, and the pair went gaily on, stopping often to chat with groups of young people, or to admire some decorations.

At last, Patty adroitly managed that they should pause near Mona, who stood talking with Lora Sayre and Jack Pennington. Patty's quick eyes saw that Mona was ill at ease, and that the others were including her in their conversation merely through a perfunctory politeness.

Patty, with her captain in tow, went up to the trio, and all joined in merry chatter. Then soon, with a gay, challenging glance at him, Patty said:

"Now Captain Sayre, you have the opportunity you wanted, to ask Miss
Galbraith to go with you to the fortune teller's tent."
